I would like to unlock the bootloader. I've enabled "Developer Mode" , "USB debugging", and "OEM unlocking". I also installed Minimal ADB and Fastboot on my Windows 10 PC. In the ADB and Fastboot terminal, it shows up as an adb device. "adb reboot bootloader" just causes the device to restart. I've only found 2 other guides, both of which are inconclusive. I've already unlocked the device with AT&T but that didn't solve my inability to unlock the bootloader. Any advice would be helpful.

i'm in the process of re-locking my bootloader in order to send it to Samsung for repair (home button not working). when i run the command line "fastboot oem lock", it just keeps hanging at "waiting on device" and nothing happens. i have the correct drivers installed. when i run "adb devices", it shows up the device. however, when i run "fastboot devices", it does not show up anything. any help on relocking my bootloader would be appreciated. Thanks!
Probably shouldn't be answering this here buuuuut...
adb reboot bootloader
and THEN
fastboot oem lock.
See what happens. You have to be in boot loader mode. Please move your questions to the Q&A section sir.
i did enter that command in order to get into fastboot. after that , i ran the command "fastboot oem lock" but it gets stuck at "waiting on device"
Update your drivers
Yea at this point I'd say its a connectivity problem. Drivers and or cable, but since you are getting adb devices to recognize, its not your cable. You should really use ubuntu, you would save yourself a lot of time, because you don't really have to deal with drivers like windows.
'sudo fastboot oem lock'
You need to be super user.
sure you went into bootloader and not recovery? because adb is seen in recovery and doesnt work in bootloader!
Hi everyone,
Today I decided to root my Mate 9.
I started out with turning 'OEM unlock' on and usb debugging. With ADB installed and the huawei drivers, I began to unlock my bootloader. On the 'EMUI Huawei' homepage I filled out my device details and obtained an unlock code. I opened ADB and checked with 'adb devices' if my device was there. It was. So I continued with typing 'adb reboot bootlader'. After that I typed 'fastboot devices'. My device was still showing up. I typed 'fastboot oem unlock CODE (with the code). On my screen I pressed 'Yes'. Bootloader unlocked.
After this step I tried to flash twrp with the command 'fastboot flash recovery xxxx.img'. I couldn't continue because every adb/fastboot command keeps failing (remote: command not allowed). Now when I boot up my phone it shows 'your device has been unlocked and can't be trusted'. Phone=unlocked, FRP=locked. I can't do anything.
Device: Mate 9 L29C432B198
What did I do wrong or what did I missed? :crying:
I had this issue at first to had to redownload the original rom via the phone recovery this will fix the frp lock then u have to unlock and flash twrp 3.1.01 that is linked in the threads on here
Did it format after it unlocked?
You can try fastboot oem relock UNLOCKCODE
Then go to Settings -> Dev options -> enable OEM Unlocking
Then unlock again.
It probably will fail though if FRP is locked, but worth a shot.
Edit: It's supposed to say
PHONE Unlocked FRP Unlock

Good Evening,
I am trying to unlock the bootloader on my Nokia C5 Endi via ADB. I have USB Debugging turned on as well as OEM Unlocking. While by device is turned on in regular use mode ADB recognizes my device perfectly. Once I enter "adb reboot bootloader" It places my phone into Fastboot Mode. I then enter "fastboot flashing unlock" and I get stuck on "Waiting for Devices" I have downloaded nearly every driver I can find on the internet since Nokia does not have a Driver Installation Page and I still continue to fail. My PC recognizes my device perfectly when it not in Fastboot Mode.
One Click Root site said my phone could be rooted. So I went through their process just for them to tell me it cant be rooted. They said it cant be rooted because the Bootloader cant be unlocked because its a Cricket Phone.
Hi My name is NS₵,
I'm here on XDA Developers to learn about rooting and downgrading Android phone software. This will be my first time doing so with my old mobile device. I have an LG K30 and I'm trying to downgrade its firmware from Android 9 to Android 8.
I have been successful at using Android Platform Tools to "adb reboot" and "adb fastboot". At the moment the fastboot command does not pick up on the plugged-in device.
The LGK30 USB connection for: File Transfer. Meaning I can "Transfer Documents and media files to the connected device". This could be the reason that fastboot isn't working. The other USB connections are: Charging, Photo Transfer and MIDI Device.
When I run the command "adb devices" I get the following response: LMX410FGf5a1e0f3 device. Then I run the command "adb reboot-loader" and then the device boots into reboot loader. The screen contains the following text:
Welcome to fastboot mode for bootloader unlock:
1. Read device
fastboot oem device-id
2. Write unlock Key
fastboot flash unlock unlock.bin
3. Check bootloader is unlocked
fastboot getvar unlocked
The drivers I have downloaded for this device are the following: LGE Mobile MTP Device and MTP USB Device
No way to root a LG K30 here is the link
